The Development Of Virtual Electrical-electronicinstrument And Application In Vocational Education

With the development of electronic computer and software,computer’s uses are becoming more and more.popular.Thus,developing virtual instrument is becoming overwhelming trend.U.S NI Corp first develops virtual instruments,produces Lab VIEW software developing platform,provides a new path for developing virtual instruments.Aimed at present update speed of domestic electrical-electronic lab instrument unable to meet social advanced technical requirement due to lack of money, thus presents disjointed situation between vocational education teaching content and social technical demand which serious affects teaching quality of vocational education and science research progress.In order to solve this problem, improve present traditional experiment teaching mode and carry out innovative improvement for experiment teaching plan by using virtual instrument as experiment equipment. Based on development and design of virtual instrument on Lab VIEW,utilized present computer software and hardware sources, achieve lab teaching through Lab VIEW to realize development of electrical-electronic virtual instrument as computer a uniform hardward platform, which has instrument’s functions and panel control buttons. Taking advantage of electrical-electronic virtual instrument to realize vocational education teaching content, not only resolves the problem of experiment hardware due to lack of money in present university, but also solves the problem of lacking lab space.It is a brand-new reform for present traditional teaching mode by using electrical-electronic virtual instrument in vocational education. Utilization of virtual instrument not only enriches experiment teaching content of electrical-electronic lab,but also adds courses which cannot be developed in traditional lab, thus deepen the knowledge of theory for students and improves their practical skills.Because virtual instruments are edited through software, virtual instruments can realize new functions through change software structure, depends on fact’s demand. Based on the revising property of virtual instruments, it provides large convenience in technical research and save money in buying instrument thus enhances the reseach ability and quality of vocational education.This project involves normal instruments design of electrical-electronic lab as LabVIEW the platform and discusses the influences of electrical-electronic virtual instrument of vocational education, the result of this project will provied useful experience in education reform of vocational education and put forword substantial proofs for popularising virtual instruments, the research result has practical value and popularisation meaning.in present vocational education.
